Hi Team,

CC1310 There is no address to save the data that the firmware will not erase this address data just like the mac address when re-flashing the firmware.

Thanks,

Hi Susan,

I am not sure if I understand you correctly, so please reach out if I missed something. But I think you are looking for a way to not erase certain areas of flash. You can choose sectors to erase when programming the device using uniflash.

Hi Sid,

Actually, I want to save the data at the address after this 0x0001f000.So that the firmware is re-swiped and the data won't be erased.

But there's so much to this address that I don't know, if that address can be used.

Regards,

Susan

Hi Sid,

How does uniflash choose which sectors to erase, I actually want the sector where my own data is saved not to be erased, and that address is 0x1e000

Hi Susan,

In setting and utilities,

Check the above setting.

This allows you to skip touching the required address.

For theCC1310 device, each sector is 4K bytes in flash. So, the address 0x1e000 is in the 30th sector. You can add 30th sector in this field and it should be protected during re-programming.
